You're not the only one. The AttemptedValue for "Location" is coming back null. I am trying to pinpoint the problem, but it's going to take me a bit, while I navigate... Any help would be appreciated. Thanks.

The problem is because the blur method is supposed to fire and bring back the Lat and Long. IT DOES NOT. Therefore a Null is passed and... the error. I haven't fixed this issue as yet. I have instead used a different service that was outlined in the walkthrough
using the different Geolocation Services on MSDN in my dinner CREATION. Hope this helps... and if anyone figures out why the Blur function is not working in the JavaScript... let us know.
